My present invention relates to foot plates or chassis more especially for roller skates.

Among the objects of the invention are to Aprovide a skate chassis of light yetrugged f 5 and strong construction having a minimum number of separate structural parts all of which are stainpings, which are easily assem'- bled and which chassis admits of ready and -secure adjustment to the length of the shoe. l0 Another object is to provide a shoe clamp of reduced number of parts and reduced 'weight, without sacrilice in the strength or effectiveness of conventional good clamps.

A feature of the invention is the pro-vision 15 of a pair of coacting sole and heel pieces, one of which has a. shank slidable relative to the other for adjustment thereof, integral guide or track means being provided to prevent displacement of the respective parts, except in if) the direction of longitudinal adjustment.

Another feature is to providel a truck frame of sheet metal clenched over one of the pieces of the foot plate and serving to guide the adjustable shank therethrough.

verse corrugations on the shank and coacting foot plate member to aid in positioning the parts in any relative setting, appropriate clamp means being provided to rigidly secure the parts in said setting.

Another feature is the toe clamp construction the individual separable clamp pieces of which are held in position against the toe piece by downturned integral winged tongues struck out from the toe piece.

In the accompanying drawings in which is shown one of various possible embodiments of the several features of this invention, Y

Fig. 1 is a top plan view of-a preferred forml of skate.

Fig. 2 is a side elevation thereof.

Fig. 3 is a bottom plan thereof.

Fig. l is a rear end elevation thereof.

'Fig'. 5 is a detail' sectional view taken on line 5-5 of Fig. 1 and on an enlarged scale.

Fig.r6 is a detail sectional viewtaken on Fig. 7 is a perspective view 'showing a de- '#1) Another feature is the provision of transshown a sheet metal sole plate 10 corrugated or embossed near its periphery at 11 for stiffening purposes,'and having an integral rearwardly extending shank 12 with parallel sides. The main length of the sole plate and its shank, has a downturnedflange 13 at each edge thereof for greater stiffness and ornamentation. A separate heel plate 14E is also provided withan integral upstanding 4ankle supporting flange 18, an integral downturned flange 15 and has also a short shank part 16 the flanges 17 of which straddle the flanges on the shank 12.

Preferably the supporting flange 18 has integral lateral ears-9 bent over the outer :'15

edges of upturned tabs 8 at the rear of the heel plate 14, the blank being laterally notched as at 7 tol determine the angle between plate l and curved ange 18. These parts are thus connected by an integral 'fr bridge 6. Y V For enhanced security the truck construction of one of therplates is constructedand related withrespectto the shankof the other to serve as a guide for the latter. For this purpose I provide an integral sheet metal truckV frame F of generally triangular or V form having an inclined'frontwall 2O and ali-inclined rear wall 21 connected by an integral axle supporting loop 22. Both sides of the front and rear wall are .provided with integra-l wings 23 extending at right angles thereto each having an integral tongue 24: protruding upward through a corresponding slot in the heel piece and clenched as shown.

The upper edges of the wings 23 abut the bottom of the plat-e 111 as at 25Qwhile thel upper edges of the front and rea-r walls of the truck frame, terminate slightly below the heel piece as at126 when the truck frame is aflixed to the heel plate, and are notched at 27 adjacent wings23. ,Space is thus afforded bet-Ween walls 2O and 21 of the truck frame for the thickness and width of shank 12, while notches 27 accommodate the flanges 13 of the shank 12. Thus the truck 'frame Vaffords a guiding gateway for the kshank 12k of the sole plate, which accordingly is securely guided by the truck frame and held thereby substantially in"c'ontact withr the herel piece, and will not curl away even though the shank be of light metal.

To avoid additional dies the truck frame F of the sole piece is identical with that described, although it does not perform the additional holding and guiding function.

For adjusting the parts I preferably 'provide a bolt having a flat head 31 countersunk at 32 in the shank 16 of the heel plate and extending through an elongatedslot 33 longitudinally of the shank 12 and tightened by a nut 34 having a lock Washer 35 in con` tact with the shank 12 of the sole piece and extending between flange .`sV 13 of the latter..

For security of theparts, I preferably provide an integral ratchet lockV construction between the heel piece and thel shank 12 of the sole piece. This ratchet comprises a series of integral transverse corrugations 36 pressed into the shank 16 of the heel piece,

vand two similar sets of narrow corrngations 3T pressed upward from between the edges of the shank 12 at opposite sides of the slot 33 therein. Thus, in adjusting the length of the chassis, after the nut k34 is loosened,

the ratchet teeth 37 can be ratcheted over i those on the heel plate 16 and when the nut 34 is again tightened inadjusted position of the skate, the ratchet lock 25 will prevent creeping that might be incurred were two smooth plates frictionally clamped.

The sole clamp comprises theusual pair of clamp pieces 40 and 41 extending under the sole piece 10 and having each a downturned lug 42. Each of these clamp pieces is held adjustably in position against the lower face of the sole piece by means of an integral tongue 43 struck down from the material of the sole piece and leaving a correspondingly shaped opening 44 therein. This tongue has a shank substantially of the thickness of the metal ofthe clamp` pieces 40 and 4l and has integra-l laterally extending wings or keys 45 sustaining the clamp piece. To permit assembly, the elongated adjustment slot 46 in each of the clamp pieces terminates in Van enlarged key slot 47 at the downturned lug 42, through which the keys are readily inserted, in sliding the clamp plates for original assembly of the device. The adjustment construction is preferably a screw having oppositely directed threads 49 and .5() on opposite halves thereof and thread- 4ed into corresponding .screw holes in the clamp lugs 42. The middle 52 of the screw Y is retained centrally in position against disvarious `objects `of the invention and is well xsuited to meet .the requirements of practical use.

I claim as new and desire to secure by Letters Patent is:
